CA 2645933

A megasonic processing apparatus and method has one or more piezoelectric transducers operating in thickness mode at fundamental resonant frequencies of at least 300 KHz. A generator powers the transducers with a variable-frequency driving signal that varies or sweeps throughout a predetermined sweep frequency range. The generator repeatedly varies or sweeps the frequency of the driving signal through a sweep frequency range that includes the resonant frequencies of all the transducers.

L'invention concerne un appareil de traitement mégasonique, et un procédé, qui comporte un ou plusieurs transducteurs piézoélectriques fonctionnant suivant l'épaisseur à des fréquences de résonance fondamentales d'au moins 300 kHz. Un générateur amplifie les transducteurs avec un signal d'attaque de fréquence variable qui modifie ou qui effectue un balayage sur toute une plage de fréquences de balayage prédéterminée. Le générateur modifie de manière répétée la fréquence du signal d'attaque, ou effectue de manière répétée un balayage de la fréquence de celui-ci, sur une plage de fréquences de balayage qui inclut les fréquences de résonance de la totalité des transducteurs.
